Thermodynamic dislocation theory: Bauschinger effect [PDF]
Physical Review E, 2018 The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here to simulate the stress-strain curves for crystals subjected to anti-plane shear-controlled load reversal. We show that the presence of the positive back stress during the load reversal reduces the magnitude of shear stress required to pull excess ...

Study of Bauschinger Effect by Reverse Shearing of 70:30 Brass
Journal of King Saud University: Engineering Sciences, 2006 Reverse shear experiments were conducted on a low stacking fault energy (SFE) material, namely 70:30 brass, and for comparison a high SFE material, namely commercial pure aluminum 1100, was chosen.

Strength Assessment of Rectangular Plates Subjected to Extreme Cyclic Load Reversals
Journal of Marine Science and Engineering, 2020 The objective of this study is to investigate the strength of the rectangular plates subjected to cyclic load reversals with varying strain ranges. The finite element solution is implemented to estimate the load-carrying capacity.

Ultimate Load Capacity and Behavior of Thin-Walled Curved-Steel Square Struts, Subjected to Compressive Load [PDF]
Civil Engineering Infrastructures Journal, 2016 There have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads.

Analysis of the Bauschinger Effect in Cold Drawn Pearlitic Steels
Metals, 2020 Prestressing steel wires usually undergo cyclic loading in service. Therefore, it is of interest to analyse certain features of their mechanical behaviour under this type of loading, such as the Bauschinger effect (BE) or the hardening rule, that fit the

Shear Banding in Binary Cu-Zr Metallic Glass: Comparison of the G-Phase With L-Phase
Frontiers in Materials, 2022 We identified two glass phases formed in three undercooled liquids of elemental Ag, binary Cu-Ag, and binary Cu-Zr alloys using molecular dynamics (MD) simulations: 1) The homogeneous L-phase arises from quenching quickly from high temperature liquid. 2)

A Study on the Effect of Restriking Process for the Stampings of HSS Sheet [PDF]
한국정밀공학회지, 2018 Recently the application of high strength steel sheets, such as DP, TRIP, and TWIP, is rapidly increasing in the automotive industry. Despite this trend, springback is still one of major obstacles that has yet to be overcome.

Transactions of the Japan Society of Mechanical Engineers, 1960 The conventional Bauschinger Effect is for static load. Is the similar effect valid for repeated load? In other words, is it true that the materials subjected to the pulsating load in one direction are easy to deform under the pulsating load in the reverse direction? If it is true, the phenomenon may be called as "Fatigue Bauschinger Effect".

A numerical study of reversible plasticity using continuum dislocation mechanics
Comptes Rendus. Physique, 2021 In this contribution, an elasto-viscoplastic fast Fourier transform-based (EVPFFT) numerical implementation of the Mesoscale Field Dislocation Mechanics (MFDM) formulation, called MFDM-EVPFFT, is applied to study the reversible plastic behavior of ...
